Application September 8, 1945, Serial No. 615,235 3 Claims. (01. 311-83)An object of this invention is to provide a collapsible table includinga table and supports hingedly connected to opposite portions thereof andarranged to be selectively moved into erect positions when the table isin use and to be folded downwardly against the bottom of. the table whenthe table is notin use.

.Another object is to provide in a collapsible table structure achannelled guide on the bottom of the table supports hingedly connectedto oppcsite portions of the table so as to bedisposed erectly andfiatwise of the table when respectively extended and collapsed, braceshinged tosaid supports and a cross-head hinged to said braces andslidable in the channel on the table.

Another object is to provide a collapsible table structure including atable having a guide on its bottom, supports hinged to and near the endsof the table and braces connecting said supports with the slide movableon said guides for selectively holding said supports in erect positionand in collapsed position against the bottom of the table.

I have shown a preferred embodiment of my invention in the accompanyingdrawings, subject to modification, within the scope of the appendedclaims, without departingfrom the spirit of my invention. In saiddrawings:

Fig. 1 is a perspective view of a collapsible table embodying myinvention with suitable associated benches;

Fig. 2 is a perspective view of the same in partially collapsedpositions and up-side-down form as when the table and benches are beingassembled or disassembled;

Fig. 3 is a perspective view of the table an benches arranged in compactform for packing or transportation from one to another location;

Fig. 4 is a bottom plan view of the folded table;

Fig. 5 is an enlarged fragmentary view in perspective of the table aswhen partially extended for use;

Fig. 6 is a cross sectional view on line 6-6 of Fig. 5;

Fig. '7 is a fragmentary view of the unit disclosed in Fig. 5 as seen onthe line 1-1;

Fig. 8 is. a bottom plan view of a bench as when it is collapsed;

Fig. 9 is a fragmentary elevation of the table;

Fig. 10 is a fragmentary section of one of the table supports and abrace therefor; and

Fig. 11 is a section on line Il--|l of Fig. 9.

Briefly described, a table embodying my improvements includes a foldabletable A adapted for use in connection with one or more but pref- .2erably two similarly foldable benches B, B of suitable type and adaptedto be arranged as shown in Fig. I. Said table and bench units areadapted to be compactly packaged for transportation from one location toanother and to occupy a minimum space.

The table unit A is approximately butnot necessarily twice the combinedwidth of the bench units B, B so that when collapsed and arranged in apackage as shown in Fig. 3 the top I of table A and the seats 2. 2 ofbenches B, B will abut and the outer edges thereof will be approximatelyflush. Table unit A has legs or end supports 3, 3 and benches B havesimilar legs or supports 4, 4 which are formed of X shape and embodyangularly connected members 3a and 4a, respectively. It is pointed outthat the crossed form of leg provides an inherently rigid type ofconstruction free from the liability to become loose after a shortperiod of use as with single vertical fold? able legs. The upperextremities of members 3a are hingedly secured to the lower side of thetable top I as at 5, and the upper extremities of the members 4a arehingedly, secured to the lower sides of the seats 2 by means of hingesB, in such a manner that the supports 3 and 4 may swing inwardly intoflatwise positions as shown in Figs. 2 and 3. The legs are crossed bymeans of a cut out in each forming what is termed a mortised joint.

Outwardly of the table supports 3 cleats 1 are attached in suchpositions on the table board so that the sides thereof will abut thesupports 3 when they are extended as shown in Figs. land 2, and saidcleats will serve to limit the outward thrust of the supports 3 beyond apredetermined extent. Similarly the bench seats 2 are: provided withcleats 8 adjacent and for abutment with the supports 4. Preferably thetable board I and the bench seats 2 may be provided with trans versecleats 9- and I0, respectively, midway between the end cleats thereof,as shown in Fig. 4 between which and the end cleats the end supports ofthe units may be nested when the units are collapsed and also serving toreinforce the table top and bench seats at points midway of their ends.

As shown in Figs. 5, 6 and 7 I have provided means for bracing the endsupports 3 and 4. Said means includes a diagonally disposed brace IIwhich is hinged at I2 at a point near the intersection of the supportmembers to each of the similar supports 3 or 4 as by means of a screweye while the other end of each brace is hinged at [3 to a cross head [4free to slide in but not to turn in a slot in the lower face of thetable. The

table top I, as shown in Figs. 5 and 6, may be channelled as at l5 toreceive longitudinal members H, I! having channels l8, I3 therein inwhich the crossheads M are slidable but not rotatable. Slots l9, l9 areformed between top flanges 20, 26 through which screws 2| are extended.Said screws also have heads 22 and flanges 23. Plates 24 are providedwith a guide 24a, Fig. 7, sliding in slots 1-9 and are interposedbetween the flanges 23 and portions 20 whereby when the screws aretightened in crossheads l4 the friction'between the crossheacls and theportions will hold the braces at a desired angle for properly holdingthe Thus, when my structure is constructed as shown and described, itmay be readily collapsed and folded into a comp-act package, after whichit and suitable accompanying benches may be table so as to fold-inwardlythereagainst when the supports 3 or 4 in either extended or retractedpositions. 7 v

It is apparent that when the supports 3, for

instance, are extended to asplane at right angles 7 'to that of thetable top I, the crossheads M will have been moved to the utmostposition toward the corresponding end of the top and when the screw-' 2'l is tightened the brace II will be effective for supporting the tableagainst collapse. But when screws 21 areloosened and the supports 3crime folded downwardly against the top 1 or seats 2 the cro's's he'adswill slide inwardly in their grooves l8, side by side while braces llwill .rest in the planes of the members 3 urges the case may be. Ifscrews 21 are then tightened the members 3 and '4 will not becomedisplaced from their retracted positions.

' In Fig. -2 I have shown an optional means of bracing the end supports3 and 4 which includes a di agonal bar 25 secured at 2'6'to saidsupports and 'attached a t-Z-I to the lower side of the table tap "I orthe seats 2 as by means of a screw or 1 lit/herein thetabl'e carries aplate 3! held by screwsfs'z andla threaded-studs? fixed t0 the plate soas t ieci'vea wing nut 34, whereby a foot 35 of Fe, brace 25 may be heldbetween said plate amisaia nut.

I prefer to so position the members 2 8 and 33 '{tli'at when braces 25are detached from and held on members 2 8 which extend through holes "36the braces, thesupports 3 and 4 may be held in the collapsed positionsshown in Figs. 2, 3, 4 and H into members 28.

with studs 33 screwed at least partially table is collapsed, a pair ofparallel guides of hollow cross section secured to the bottom surface ofthe table and having slots formed in the bottom walls'thereof,crossheads slidable in the channels of said guides, elements borne bysaid c'rossheads and having portions extended through said slots forlocking said crossheads on said guides when said elements areappropriately actuated, and braces hinged to said supports and toysaidcrossheads for holding said supports in erect positions to support saidtable.

2. A folding table structure as characterized in claim 1 wherein each ofsaid supports includes two members secured together and crossed at apoint intermediate of the ends thereof and said braces are hinged toeach support at points near the intersection of its crossed members. 5 x3.- A folding table structure as characterized in claim lwherein thebottom side of said table is formed with a longitudinal channel midwaybetween the lateral margins of the table and said guides are seatedin-saidcha'nnel with their bottom walls flush with the bottom surface ofthe table so that said supports when collapsed will lie in contact withthe table.
